Filtration acquisitions complete

Posted: Wednesday 26th October 2011

Bluewater Bio, a global specialist in the treatment of wastewater, has completed the acquisition of a portfolio of advanced multimedia filtration technologies, including the Spruce Media Filter, from FilterClear Ltd of Glasgow in the UK. The acquired technologies are applicable to both the water and wastewater treatment markets globally, which was a key driver behind the acquisition reflecting Bluewater Bio’s existing international footprint. The technologies will be marketed by Bluewater FilterClear Ltd, a newly formed subsidiary.

FilterClear technologies have to date shown impressive performance in over 60 commercial installations, including applications in desalination, municipal wastewater, and potable water filtration. Key defining features that make the technology attractive to existing customers include the unusually high throughput rate and solids retention that can be achieved, the high dirt holding capacity and low volume of backwash waste, making it potentially the best available technology for a number of important filtration applications.

The high throughput of 20-50 m3/h enables a highly compact footprint and delivers associated capital expenditure savings on space, filter vessels and peripheral equipment. Spruce media provides unusually efficient suspended solids removal to produce filtrate to a high level of quality normally associated with membrane and cartridge filtration. The high dirt-holding capacity of the media enables longer cycles between backwash and minimum backwash volume. Together these attributes enable low energy and reduced or zero chemical consumption.

The filter comprises typically four layers of media with highly specified materials, densities, particle sizes distribution and shape characteristics. There are four variants for optimum performance in different applications or water types, and an extensive, growing database of performance in over 60 commercial installations with different water characteristics and suspended solids particle loads.
